Once again, people on this list have _very_ limited psychic powers, and not much time trying to infer what your issue is all about: nobody knows what you are trying to do (non-matching Xenomai versions, undefined hardware), the way you do it (undefined kernel config), and what your machine tells you when you try it (no sensible boot log provided yet). We are not there looking over your shoulder when all that happens, so we don't know. Really. Please check the mailing list archive _thoroughly_ first, to solve the most obvious issues. > > > > Best Regards, > > Hemal Bavishi > > Principal Engineer > > > > KPIT Infosystems GmbH | Franziska - Bilek - Weg 9 | 80339 Munich > > Phone: +49(0) 89 45 23 5 83 - 06 | Mobile: +49 162 426 9950 | Fax: +49 > (0) 89 45 23 5 83 - 07 > > http://www.kpitcummins.com| mailto:[email protected] > > Frankfurt Branch Office: > KPIT Infosystems GmbH | Mainzer Landstrasse 176 | 60327 Frankfurt | > Germany > > Geschäftsführer/Managing Director: Sanjay Mandal > Handelsregister/Commercial Register: München/Munich HRB 163288 > Sitz der Gesellschaft/Place of Business: München/Munich | > Umsatzsteuernummer/VAT Number: DE251280557 > > Disclaimer: This message contains information that may be privileged > or confidential and is the property of KPIT Cummins.
